---------------------------

             Summary: Decide detailed package structures for timeline service v2 components
                 Key: YARN-3166
                 URL: https://issues.apache.org/jira/browse/YARN-3166
             Project: Hadoop YARN
          Issue Type: Task
            Reporter: Li Lu


Open this JIRA to track all discussions on detailed package structures for timeline services
v2. This JIRA is for discussion only so I don't think it should have any assignees. 

For our current timeline service v2 design, aggregator (previously called "writer") implementation
is in hadoop-yarn-server's:
{{org.apache.hadoop.yarn.server.timelineservice.aggregator}}

In YARN-2928's design, the next gen ATS reader is also a server. Maybe we want to put reader
related implementations into hadoop-yarn-server's:
{{org.apache.hadoop.yarn.server.timelineservice.reader}}

Both readers and aggregators will expose features that may be used by YARN and other 3rd party
components, such as aggregator/reader APIs. For those features, maybe we would like to expose
their interfaces to hadoop-yarn-common's {{org.apache.hadoop.yarn.timelineservice}}? 

Let's use this JIRA as a centralized place to track all related discussions.
